Non-road engines (or non-road mobile machinery in the European union) are engines that are used for other purposes than a motor vehicle that is used on a public roadway. [1] The term is commonly used by regulators to classify the engines in order to control their emissions.
Non-road engines are used in a wide range of applications which may include machinery and non-road vehicles. [2] [3] In many jurisdictions, the term non-road engine is assumed to refer to the engines that have mobility or portability, which is separated from the term stationary engine. [4] The definition of non-road engine may explicitly exclude certain non-road vehicles such as aircraft, locomotives, and ocean-going marine vessels. [5]
There are many classifications of the non-road engines based on the jurisdictions. The following are common classifications: [2] [6]
In certain jurisdictions, stationary engines that are diesel powered may be classified as non-road engines. [4]
The rationale for establishing emission standards for non-road engines is that they are a significant source of pollution. The engines of on-road vehicles have advanced emission controls which are not found on those non-road engines. The non-road engines also emit air pollution particles at much higher rates. [6]
The emission standards are based on the engine classifications and vary in various jurisdictions. The main model regulations that are used by many countries are the United States Environmental Protection Agency through the section 213 of the Clean Air Act (42 U.S.C. 7547) and the directive of the European Commission (the "mother" Directive 97/68/EC, the amendments Directive 2002/88/EC, Directive 2004/26/EC, Directive 2006/105/EC, Directive 2011/88/EU and the last amendment Directive 2012/46/EU). The directives cover diesel engines, spark-ignition engines, constant-speed engines, railcars, locomotives and inland waterway vessels. [4] [7]
In Europe, the term "non-road mobile machinery" (NRMM) is used to clarify that the definition refers to non-road engines that are capable of self-propulsion. [7]
In the European Union, in 2023, the Commission and the Council proposed to harmonize road safety requirements to ease non-road mobile machinery (such as lawn mowers, harvesters or bulldozers) to circulate on public roads and replace local European union member states regulations. This would only apply to machine with maximum speed greater than 6 km/hour (around 4 miles per hour). Next legislative step would be in the European parliament. [8]
The standards for non-road diesel engines are more harmonized. Many countries adopt the emission standards derived from either the US or the European models.
Canada adopted the US standards in 1999. Korea modeled its Tier 2 standards from the US Tier 2. Russia adopted the European Stage I standards. Turkey adopted the European standards but with different implementation dates. China adopted the European Stage I/II standards in 2007.
India introduced its own standards in 2006 called Bharat (CEV) Stage II (based in part on European Stage I) and Bharat (CEV) Stage III (based on US Tier 2/3). Japan introduced its own standards that are similar but not harmonized to the US Tier 3 and Europe Stage III A. Brazil adopted the resolution in 2011 to set emission standards that are equivalent to US Tier 3 and European Stage III A. [4]
In Australia, the definition includes some stationary engines such as electric generators and pumps. [6]
Electromagnetic compatibility (EMC) is the ability of electrical equipment and systems to function acceptably in their electromagnetic environment, by limiting the unintentional generation, propagation and reception of electromagnetic energy which may cause unwanted effects such as electromagnetic interference (EMI) or even physical damage to operational equipment. The goal of EMC is the correct operation of different equipment in a common electromagnetic environment. It is also the name given to the associated branch of electrical engineering.
A stationary engine is an engine whose framework does not move. They are used to drive immobile equipment, such as pumps, generators, mills or factory machinery, or cable cars. The term usually refers to large immobile reciprocating engines, principally stationary steam engines and, to some extent, stationary internal combustion engines. Other large immobile power sources, such as steam turbines, gas turbines, and large electric motors, are categorized separately.
Emission standards are the legal requirements governing air pollutants released into the atmosphere. Emission standards set quantitative limits on the permissible amount of specific air pollutants that may be released from specific sources over specific timeframes. They are generally designed to achieve air quality standards and to protect human life. Different regions and countries have different standards for vehicle emissions.
Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, or coal. According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle. It often disperses downwind in a pattern called an exhaust plume.
On commercial products, the presence of the logo means that the manufacturer or importer affirms the goods' conformity with European health, safety, and environmental protection standards. It is not a quality indicator or a certification mark. The CE marking is required for goods sold in the European Economic Area (EEA); goods sold elsewhere may also carry the mark.
Ultra-low-sulfur diesel (ULSD) is diesel fuel with substantially lowered sulfur content. Since 2006, almost all of the petroleum-based diesel fuel available in Europe and North America has been of a ULSD type.
On-board diagnostics (OBD) is a term referring to a vehicle's self-diagnostic and reporting capability. In the United States, this self-diagnostic is a requirement to comply with Federal Emissions standards to detect failures that may increase the vehicle tailpipe emissions to more than 150% of the standard to which it was originally certified.
The European emission standards are vehicle emission standards for pollution from the use of new land surface vehicles sold in the European Union and European Economic Area member states and the United Kingdom, and ships in EU waters. The standards are defined in a series of European Union directives staging the progressive introduction of increasingly stringent standards.
Type approval or certificate of conformity is granted to a product that meets a minimum set of regulatory, technical and safety requirements. Generally, type approval is required before a product is allowed to be sold in a particular country, so the requirements for a given product will vary around the world. Processes and certifications known as type approval in English are often called homologation, or some cognate expression, in other European languages.
A diesel particulate filter (DPF) is a device designed to remove diesel particulate matter or soot from the exhaust gas of a diesel engine.
A portable emissions measurement system (PEMS) is a vehicle emissions testing device that is small and light enough to be carried inside or moved with a motor vehicle that is being driven during testing, rather than on the stationary rollers of a dynamometer that only simulates real-world driving.
United States vehicle emission standards are set through a combination of legislative mandates enacted by Congress through Clean Air Act (CAA) amendments from 1970 onwards, and executive regulations managed nationally by the Environmental Protection Agency (EPA), and more recently along with the National Highway Traffic Safety Administration (NHTSA). These standard cover common motor vehicle air pollution, including carbon monoxide, nitrogen oxides, and particulate emissions, and newer versions have incorporated fuel economy standards.
A vehicle category classifies a land vehicle or trailer for regulatory purposes.
Bharat stage emission standards (BSES) are emission standards instituted by the Government of India to regulate the output of air pollutants from compression ignition engines and Spark-ignition engines equipment, including motor vehicles. The standards and the timeline for implementation are set by the Central Pollution Control Board under the Ministry of Environment, Forest and Climate Change.
The Ecodesign Directive of the European Union establishes a framework to set mandatory ecological requirements for energy-using and energy-related products sold in all 27 member states. Its scope currently covers more than 40 product groups, which are responsible for around 40% of all EU greenhouse gas emissions.
A Skid mount is a popular method of distributing and storing machinery and usually-stationary equipment for the military and industry on its own or with other units as part of a modular system. The machinery at point of manufacture is permanently mounted in a frame or onto rails or a metal Pallet. The equipment can then be easily secured and transported and used as a unit. A unit such as a fire-fighting Skid unit may also be temporarily placed onto a vehicle to equip it for a task. They often have standard sized holes for a forklift truck to slide into it to lift it safely.
The Worldwide harmonized Light vehicles Test Procedure (WLTP) is a global standard for determining the levels of pollutants, CO2 emissions and fuel consumption of traditional and hybrid cars, as well as the range of fully electric vehicles.
Industry of Machinery and Tractors is a Serbian manufacture company which produce and sells tractors and agricultural machinery. It is headquartered in Belgrade, Serbia. In April 2018, IMT was sold to the Indian company TAFE.
The Machinery Directive, Directive 2006/42/EC of the European Parliament and of the Council of 17 May 2006 is a European Union directive concerning machinery and certain parts of machinery. Its main intent is to ensure a common safety level in machinery placed on the market or put in service in all member states and to ensure freedom of movement within the European Union by stating that "member states shall not prohibit, restrict or impede the placing on the market and/or putting into service in their territory of machinery which complies with [the] Directive".
